/**
 * An `HttpAgent` that tolerates the AG-UI event streams real agents emit.
 *
 * @deprecated Pass a plain `HttpAgent` instead. Channels now tolerate these
 * streams by default — `createChannel` coerces the offending field on the wire
 * (opt out with `sanitizeAgentEvents: false`), so nothing needs a special agent
 * class. This class is kept, unchanged, so existing code keeps working; it will
 * be removed once `@ag-ui/langgraph` stops emitting the null (OSS-691). Note it
 * still replaces the whole stock transform, so it also forgoes protobuf
 * content-type negotiation and the graceful `AbortError` → `RUN_ERROR`
 * conversion that the default path keeps.
 *
 * `@ag-ui/client`'s stock transform re-validates every streamed event against a
 * strict Zod schema. Some events that `@ag-ui/langgraph` legitimately emits fail
 * it (notably a `TOOL_CALL_START` whose `parentMessageId` is `null`: "Expected
 * string, received null"), and a single rejected event aborts the entire run.
 * That breaks LangGraph interrupts / human-in-the-loop on Teams, where the tool
 * call that triggers the interrupt carries exactly that shape.
 *
 * The bridge talks to a trusted runtime, so rather than re-validate its output
 * we use the same SSE parse the stock path wraps (`parseSSEStream`) and coerce
 * the known nullable-string fields. This deliberately drops the stock
 * transform's *entire* strict Zod re-validation step (not just the offending
 * field). This is acceptable only because the runtime is trusted and `runHttpRequest`
 * still throws on transport/HTTP errors. The first coercion logs a one-time
 * breadcrumb so the workaround is visible in production. Revert to the stock
 * transform (`transformHttpEventStream`) once upstream makes the fields
 * nullable.
 *
 * Pointing a Teams bot at a LangGraph (or any other AG-UI) agent needs no
 * special class:
 *
 * ```ts
 * import { HttpAgent } from "@ag-ui/client";
 * const agent = new HttpAgent({ url: process.env.AGENT_URL! });
 * ```
